Head count, arrival times, and a meal plan. I usually do a Friday or Saturday night for 20 while primitive camping on a gravel bar in January. Your meal plan should include the gear you intend to cook it with so you know it is there. It helps to have a big stock pot, a couple of campfire grills, full size two burner propane stove, big skillet, a couple chef knives v pocket knives, cutting boards, and some portable tables, a couple dutch ovens. Pre cook and vac pack what you can so it wont get soggy in a cooler. Have a great time guys! Wish I could make it, but I have another commitment.
